About the Nifty Numpad before sockets PCB

Nifty Numpad before sockets is an open source RP2040/RP2350 PCB design by Acliad, published on GitHub under the CERN-OHL-1.2 license. It is a 4-layer board measuring 118.4 × 131 mm, with 170 components from 54 distinct parts.

Its main chip is the RP2040, from the RP2040/RP2350 family. Other key parts include the 3.3V, C5359995, SN74LVC1T45DCK and W25Q40CLSNIG. By type, the board carries 66 diodes, 52 capacitors, 35 switches, 8 resistors, 5 ICs and 3 connectors.

It belongs with the keyboards designs in this gallery.

From the project

Full sized numpad with an extra row and two extra columns of macro keys. It was created as a companion to my TKL keyboard for CAD design.

Nifty Numpad is a full sized numpad with an extra row and two extra columns of macro keys. It was created because I wanted a companion to my TKL keyboard for work. My main workflow involves heavy use of ECAD programs, so the design was tailored for that, but it is generic enough to be nice for many workflows!

The main features are: - Full sized numpad with row of macro/function keys on the top - Two extra columns of macro keys - Cherry MX style socketed switches - Backlit keys - 3D printable case (FDM or resin)
